Therefore, GCD of numbers 833, 489, 21, 376 is 1

Given Input Data is 833, 489, 21, 376

Make a list of Prime Factors of all the given numbers initially

Prime Factorization of 833 is 7 x 7 x 17

Prime Factorization of 489 is 3 x 163

Prime Factorization of 21 is 3 x 7

Prime Factorization of 376 is 2 x 2 x 2 x 47

The above numbers do not have any common prime factor. So GCD is 1

Step1:

Let's calculate the GCD of first two numbers

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(833, 489) = 407337

GCD(833, 489) = ( 833 x 489 ) / 407337

GCD(833, 489) = 407337 / 407337

GCD(833, 489) = 1

Step2:

Here we consider the GCD from the above i.e. 1 as first number and the next as 21

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 21) = 21

GCD(1, 21) = ( 1 x 21 ) / 21

GCD(1, 21) = 21 / 21

GCD(1, 21) = 1

Step3:

Here we consider the GCD from the above i.e. 1 as first number and the next as 376

The formula of GCD is GCD(a, b) = ( a x b) / LCM(a, b)

LCM(1, 376) = 376

GCD(1, 376) = ( 1 x 376 ) / 376

GCD(1, 376) = 376 / 376

GCD(1, 376) = 1

GCD of 833, 489, 21, 376 is 1
